Method

Getting Started

Lat/Long: I use a Mac, and its Map program provides an easy way to turn an address into a Lat Long. You can also use maps.google.com.

Spreadsheet. I used a Google Sheet. You can also load data into excel (csv) and drop into Google Maps.

Google Maps. You need a Google login for this.

Making the Map

Create Google Sheet (or spreadsheet) with four columns

A. Address B.Lat C.Long D. NBN Status – in rollout (yes/no)

Get the Lat Long. In Apple Maps, pick an address, Drop a pin = Right Click. Click (i).
Copy address into Column A. Copy Lat/ Long in Col B,C.
Alternatively, in Google Maps, right click What's here to get the Lat/Long of any point. You can also find a Lat/Long with Google Maps API; by inserting and address into: http://maps.googleapis.com/maps/api/geocode/json?address=ADDR where ADDR = 12carlislecrescent,hughesdale,vic eg Link
